Application filed .Tune 2,

To all whom it may concern:

Be it known that I, FRANK BEISLER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Door Silencers, of which the following is a specification.

This invention relates to a door silencer, particularly designed for use in connection with screen doors or other doors of relatively light weight, and an object of the invention is to provide a combined buffer and silencer which is comparatively simple in construction and will buff or cushion the closing action of the door irrespective of the number of times the door rebounds.

Another object of the invention is to provide a bumper or silencer for doors as specified, which will swing under its own action into buffing position upon the opening of the door, one which may be reversed to adapt it for door swinging in either direction.

Other objects of the invention will appear in the following detail description, and in the accomanying drawings wherein Figure 1 is a perspective view of the improved door silencer or bumper.

Figure 2 is a side elevation of the bumper showing it in its normal position when the door is closed.

Figure 3 is a side elevation of the bumper showing it in position assumed when the door is open.

Figure 4 is a side elevation of the bumper showing it in the position assumed when the door is partly closed.

Figure 5 is a detail section through the door silencer or bumper.

Referring more particularly to the drawings, the improved door silencer or bumper comprising the attaching plate 1 which is rectangular in shape and is attached to the door frame 2 in any suitable manner, with its edge flush with the edge of the frame against which the door 3 strikes. A boss 4 is struck from the plate 1 and the bumper proper 5 is pivotally connected to the plate 1 by means of the boss l and a suitable bolt 6. The bumper 5 includes the body lever 7 which includes the segmental portion 8 having the arm 9 projecting outwardly from its lower outer corner and at an acute angle to the radii of the segment 8. The segment is provided and projects rearwardly from 1924. Serial No. 717,414.]

the pivot b0lt'6 of the bumper 5, so as to provide suflicient weight to force thearm' 9 outwardly into horizontal position, shown in Figure 3 of the drawings, when the door 3 is open. Arubber bumper 10 is mounted on the outer end of the arm 9, and it is engaged by the door 3 during the closing of the door. The arm 9 has a stop catch 11 thereon which engages the stop tongue 12 during the outward movement of the arm 9 and limits the pivotal movement of the bumper proper so as to hold the arm 9 in horizontal position. The stop tongue 12 is preferably cut from. the attaching plate 1. A balancing lever 14: is pivotally connected, as shown at 15, to the arm 9, and it has an upstanding portion 16 which is enlarged as shown at 17 to provide a counter-balancing weight. The balance lever 14; has a notch 18 on its inner end which moves upwardly for engagement against the tongue 12 during the closing of the door 3 so as to permit the resilient bumper 10 to engage.

the door during its closing and upon each rebound of the door, thereby eliminating the undesirable slamming sound caused by the closing or slamming of the door, both in its initial and rebound movements.

The weight of the door, after it ceases to rebound, and the force of the striking of the door against the bumper will be relieved, which will permit the balance lever 14 to swing into its normal horizontal position, and will allow the bumper proper 5 to swing inwardly into its normal position assumed when the door is closed, and as shown in Figure 2 of the drawings.

The construction of the improved door silencer is such that it may be reversed, that ispositioned with the arm 9 extending in the opposite direction to that in which it is shown in Figures 2 and 3 of the drawings, permitting its use with doors irrespective of the direction in which they swing.

It is, of course, to be understood, that the invention may be constructed in various other manners and the parts associated in diflerent relations, and therefore, I do not desire to be limited in any manner, except as set forth in the claims hereunto appended.

What I claim is 1. A door silencer comprising an attaching plate having a stop tongue struck therefrom, a bumper lever pivoted to said attaching plate, a resilient bumper on one end lever and having a counter-balance thereon,

and provided with a notch for engagement with said stop tongue to regulate the inward pivotal movement of said bumper lever. v

2. A door silencer comprising an attaching plate having a stop tongue struck therefrom, a bumper lever pivoted to said attaching plate, a resilient bumper on one end of said bumper lever, a stop on the bumper lever adaptedto engage said tongue to limit the outward movement of the lever,' and a balance lever pivotally carried by the bumper lever and having a counter-balance thereon and provided with a notch for engagement with said stop tongue to regulate the inward pivotal movement of said bumper lever, said bumper lever having a segment shaped portion which is pivoted at its apex to the attaching plate to provide suflicient weight to the bumper lever to swing it outwardly into operative positionupon the opening of the door with which it is associated.

In testimony whereof I aflix my signature.

FRANK BEISLER.
